FEEDING ATTACHMENT FOR PLANlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 245,608, dated August 16, 1881.

' I Application'filed December 30,1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN J. BURK, a citizen of .the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Feeding Attachments for Planing or other Machines, of which the following is a specification.

The object of myinvention is to provide the means for automatically feeding the staves or boards; and it consists of a feed-box to hold the articles to be fed, having the front end adjustable vertically, a pressing-board hinged to the upper rear end of the box, having its front end provided with a weight for the purpose of holding the front ends of the staves down and in line with each other, in combination with a rough-faced or grooved feedingroller, a roller at the lower rear end of the feed-box, and a small loose roller in front, as and for purposes which will be more clearly hereinafter shown.

My invention further consists in providing the pressing-board with a sharp-edged metal strip projecting down from its lower face and arranged longitudinally, so as to guide the staves or boards as they are pushed forward into the feed-box, all of which will be more clearly understood by reference to the drawings, in which- Figure l is a vertical longitudinal section through the feed-box and connections, and a side elevation of the feeding-rollers. Fig. 2is a plan or top view of the same. Fig. 3 repre sents a face view of the under side of the pressing-board; Fig. 4, an end View of the same, and Fig. 5 is a top view of the feeding-roller.

A is the feed-box a b, the sides of the same.

B is the vertically-adjustable front piece for the purpose of adjusting the device for staves or boards of different thicknesses. It is held in place by the set-screws c, or other suitable means for holding it at any point desired.

(3 represents the pressing-board d, a weight placed at the forward end thereof. Itis hinged or pivoted to the rear upper end of the feedbox by hinges or pivots 0. Its object is to press down the ends of the staves at the front end of the box, so as to insure the entering of the stayes through the opening under the end of piece B, so as to make the feeding of a winding or warped stave more certain. A winding stave or board would present the end with a corner turned, or not in line with the opening under the part B. Consequently it would not enter, and would thereby endanger the breaking of some part of the mechanism.

It will be readily seen that a suitable press ure at the entering ends of the staves would hold them together, so as to be sure to enter, while a pressure covering the whole length of the staves or boards in the feed-box would not operate well in practice for the reasons above given.

The lower side of the pressingboard 0 is provided with a sharp-edged strip of metal, 0, to cause the staves to pass straight into the feed-box, after having been properly entered, by placing the ends of the staves (at the center or middle of the end) against said strip.

To assist the lower board or stave, f, to move forward as it drops down in place after a board has been taken from under it, asmoothfaced roller or wheel,D,is arranged at the rear end of the box, as shown in Fig. 1. It receives a motion in the direction of the arrow. h, alittle faster than the feeding movement of the staves, by means of a belt, I, and pulley, J, which connects with the pulley K on the shaft of roller G.

To prevent two thin boards or staves from being pushed under the end piece, B, a small loose roller, E, kept down by a spring, F, is arranged in front of the piece B. It will be seen that as the lower board is forced forward by the notched or toothed wheel G, and that its movement is thereby arbitrary, the board above it would have a tendency to move forward only by the friction between the two, and that if the force of the wheel E is sufficient to overcome the friction, it will answer the purpose.

The feeding-roller G receives its motion by a chain -belt, G, or other gearing, from the roller H on the machine into which the staves are to be fed; or it may be operated independently from a pulley arranged on the shaft of the feed-roller G. The bottom of the box L is provided with an opening, M, so that the teeth 6 of the feed-roller G may reach the stave or board to be fed.

I claim as my invention- 1. The combination of the box A, hinged or bination with the roller D, feedingroller G, pivoted pressing-board 0, provided with the and loose roller E, provided with a spring, F, strip C on its under side, with the smoothas and for the purposes specified.

faced roller D and the rough-faced feeding- JOHN J. BURK. 5 roller G, as and for the purposes described. Witnesses:
